Porphyrins with enhanced multi-photon absorption cross-sections for photodynamic therapy
-
, (2008/06/13)
A method of increasing the multi-photon absorption cross-section of a porphyrin-based photosensitizer by attaching at least one TPA-chromophore at the meso- or beta-positions of a porphyrin structure of the porphyrin-based photosensitizer, and at least on
